This paper presents a new realization of standards for ac-dc difference at voltages ranging from 1 to 4 V and frequencies of up to 1 MHz. This work has mainly been focused on improving the determination of the components of ac-dc difference that most significantly contributed to the uncertainty of the previous realization. These components are the ac-dc difference due to skin effect, transmission...
The paper presents a new realisation of standards for AC-DC difference at voltages from 1 V to 4 V and frequencies up to 1 MHz with standard uncertainties less than 5 muV/V at 1 MHz.
